What is a roof pitch?
- A roof pitch refers to the steepness of the roof and can also be referenced as the slope, incline or angle. Roofers typically refer to it as a pitch and can be found by factoring the rise over a 12 inch run.
Why figure what your roof pitch is?
- Helps determine what materials are suitable for your roof. For example, a roof with a pitch of 1 cannot use metal shingles.
What is the multiplier?
- A flat roof has a pitch of 1, meaning the material needed is 1 times the size of the roof. Based on the pitch, you can use the multiplier to determine the amount of material needed for a roofing project.
After safely measuring your roof to discover the pitch, you can use the graph below to calculate your roof pitch in degrees and multiplier.
